Abstract

Interventions to extend lifespan and healthspan may affect male and female organisms differently.

  • Sex-specific differences in baseline lifespan and characteristics such as body size and metabolism may influence responses to lifespan-extending interventions.
  • Current literature indicates that males and females respond differently to various interventions aimed at extending lifespan.
  • Differences in gonadal hormone levels or chromosome status could play a role in how aging interventions affect males and females.
  • Understanding sex as a biological variable in aging may uncover distinct strategies for improving healthspan and addressing age-related diseases.
